2016-09-21net: pch_gbe: Make 64 bit safePaul Burton1-10/+10
The pch_gbe driver previously casted pointers to & from unsigned 32 bit integers in many locations. This breaks the driver on 64 bit systems, producing streams of compiler warnings about mismatched pointer & integer sizes and then failing to keep track of addresses correctly at runtime. Fix the driver for 64 bit systems by using unsigned longs in place of the previously used 32 bit integers.

2016-09-21net: pch_gbe: Use dm_pci_map_bar to discover MMIO basePaul Burton1-5/+3
Reading the PCI BAR & converting the result to a physical address is not safe across all architectures. For example on MIPS the virtual:physical mapping is not 1:1, so we cannot directly make use of the physical address. Use the more generic BAR-mapping function dm_pci_map_bar to discover the MMIO base address, which should work across architectures.

2016-08-22net: davinci_emac: Restore the internal MDIO accessors return valueskarl beldan1-7/+6
The spatch series converting legacy drivers from miiphy_register to mdio_register changed the return convention of the davinci_emac internal MDIO accessors, making the internal code relying on it misbehaving: no mdiodev get registered and U-Boot crashes when using net cmds in the context of the old legacy net API. ATM davinci_emac_initialize and cpu_eth_init don't return a proper value in that case but fixing them would not avoid the crash. This change is just a follow-up to the spatch pass, the MDIO accessors of the mdiodev introduced by the spatch pass retain their proper values.

2016-07-26net: sun8i_emac: Drop redundant and incorrect setting of syscon registerChen-Yu Tsai1-9/+1
In sun8i_emac_board_setup, the driver partially configures the syscon register for H3 EPHY. However, the settings are incomplete, and completely unusable. The correct settings are later set in sun8i_emac_set_syscon, but the incorrect CLK_SEL setting persists. It is incorrect to use CLK_SEL to select 25 MHz, as the SoC does not have a 25 MHz clock the EPHY can use. This patch removes the setting of the syscon register in board_setup, and also moves set_syscon above mdio_init. While mdio_init does not access the PHY, it is better to have the PHY parameters setup before the MDIO bus is registered. Fixes: a29710c525ff ("net: Add EMAC driver for H3/A83T/A64 SoCs.")

2016-06-21net: rtl8169: fix switching between adaptersStephen Warren1-4/+9
The rtl8169 driver uses a global variable to store the register address of the adapter being operated upon. This is updated to point at the correct adapter when sending or receiving a packet, or shutting down the adapter, but not when initializing the adapter. Consequently, switching between different adapters within the same U-Boot runtime does not work correctly since the driver programs the wrong registers during rtl8169_eth_start() -> rtl8169_common_start() -> rtl8169_hw_start(). Note that since rtl8169_eth_stop() does set the global variable, the second consecutive attempt to use the "new" adapter did work even before this patch, because each time network usage is shut down, the network core calls stop, which sets the variable so that the next start does actually initialize the hardware, and the adapter works. Equally, rtl8169_eth_probe() calls rtl_init() which sets the global, so if using only a single device, or if picking the "right" device (based on probe order) when multiple devices are present, ioaddr will already be set correctly from the get-go, so the issue does not occur.
